Abstract: During the World War Ⅱ, American book publishing industry began to go abroad, explored the global market vigorously and achieved rapid rise, surpassing the powerful publishing countries like British and French. The rise is closely related to the drastic changes in the wartime of the international book publishing environment, the development of the US publishers to the book market, the special geographical location and publishing conditions of the United States and the strong support of the US federal government. Its rapid rise during World War Ⅱ was the inherent requirement of the United States trying save the people in the European occupation zone, actively shaping the new image of the United States and improving morale in order to win the war. It was also the inevitable result of the United States trying to seek global cultural hegemony after the war.
